Abstract

PROBLEM TO BE SOLVED: To obtain a large amount of aromatic blowing while increasing the volume of an aromatic storing part by arranging an air reserving part at just upstream side of a sucking port in a blow chamber where a fan for sucking and blowing-out an aroma which is discharged from the aromatic storing part is disposed and permitting an air intake passage having the aromatic storing part to communicate with the air reserving part. SOLUTION: When the fan 26 is driven by a motor 24, air is sucked from the sucking port 36 to the blow chamber 35 by way of the air intake passage 48 from the air intake port 47 of a cover 42. Simultaneously, the aroma in an aromatic storing cassette 41 is sucked from the port 36 to the chamber 35 through an aromatic intake passage 49 passing the entrance 43A and the exit 43B of the cassette 41 from the air intake port 47 of the cover 42. As a result, the aroma is generated in the chamber 35 and blown-out to the outside of the chamber from the blow-out port 37 of a blow case 12. In this case, the recessed air reserving part 51 is arranged at the just upstream side of the intake port 36 of the chamber 35 and also the narrow air intake passage 48 arranged between the cassette 41 and the cover 42 is made to communicate with the air reserving part 51.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a fragrance device.

[0002]

2. Description of the Related Art As described in Japanese Patent Application Laid-Open No. 10-85313, a fragrance storage section is provided in a housing, a fan driven by a motor is provided in a blower chamber, and scent coming out of the fragrance storage section is supplied to the blower chamber by the fan. There is a fragrance that sucks and blows out.

However, in the fragrance device, the volume of the fragrance storage portion is made as large as possible with respect to the outer dimensions of the housing, and as a result, the air intake passage formed in the housing around the fragrance storage portion to the air blowing chamber is formed. If the flow passage area is small, sufficient air cannot be taken in when the fan is operated, and the amount of air blown out cannot be increased.

SUMMARY OF THE INVENTION It is an object of the present invention to increase the volume of fragrance blow-out air while increasing the volume of the fragrance storage section as much as possible in the fragrance device.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a fan driven by a motor is provided in a blower chamber, and the fan is provided in a fragrance device which suctions and emits scent from a flavor storage section into the blower chamber. An air reservoir is provided immediately upstream of the suction port of the blower chamber to be used, and a narrow air intake passage provided around the perfume storage is communicated with the air reservoir.

DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 to 3, the fragrance device 10 has a three-layer structure in which a motor case 11, a blower case 12, and a fragrance tank 13 are laminated.

The motor case 11 includes a battery 23, a motor 2
4, the output shaft 24A of the motor 24 penetrates a shaft hole 25 provided on the top surface of the motor case 11, and a fan 26 is press-fitted into the penetrating end.

The blower case 12 is engaged with the motor case 11 and the top surface of the motor case 11 and the upper partition plate 33 are engaged.
And a side partition plate 34 to form a blower chamber 35, and a fan 26 is disposed at the center of the blower chamber 35, and an upper partition plate 33 is provided.
The suction port 36 provided at the center of the fan 26 is disposed above the center of the fan 26, and the blowout port 37 provided on the side of the blower case 12 corresponding to the substantially C-shaped cut of the side partition plate 34 on the outer peripheral side of the blower chamber 35 is provided. Have been placed.

The fragrance tank 13 includes a fragrance storage cassette 41.
And a cover 42. Perfume storage cassette 4
Numeral 1 is a bottomed hemisphere, and constitutes a fragrance storage section for storing fragrance 1 (fragrance). The fragrance storage cassette 41 is
One or more inlets 43A are opened in the top surface of the sphere, and an outlet 43B is opened in the center of the bottom surface. The fragrance storage cassette 41 is placed on the support projection 38 on the upper surface of the upper partition plate 33 of the blower case 12, and connects the cylindrical portion 44 to the central suction port 36 of the upper partition plate 33.
Has been placed.

The cover 42 is attached to and detached from the blower case 12. The cover 42 is provided with an air intake 47 on the top surface of the sphere, and the air intake passage 48 (the air intake passage 48 is a fragrance storage cassette) between the cover 42 and the outer surface of the fragrance storage cassette 41 in a state of being engaged with the blower case 12. (Which extends to the suction port 36 between the bottom surface of the upper surface 41 and the upper surface of the upper partition plate 33 of the blower case 12).

Therefore, when the motor 24 drives the fan 26, the fragrance device 10 causes the air to be drawn from the air inlet 47 of the cover 42 through the air inlet passage 48 passing between the cover 42 and the perfume storage cassette 41. Blast chamber 35
And the air intake 47 of the cover 42
Then, the fragrance in the fragrance storage cassette 41 is sucked into the blower chamber 35 from the suction port 36 by the fragrance intake passage 49 passing through the entrance 43A and the outlet 43B of the fragrance storage cassette 41. As a result, the air and the fragrance are mixed in the blower chamber 35 to generate fragrance, and the fragrance is blown into the room from the outlet 37 on the side surface of the blower case 12.

However, in the fragrance device 10, the fan 2 driven by the motor 24
A recessed air reservoir 51 is provided immediately upstream of the suction port 36 of the blower chamber 35 in which the fragrance 6 is provided.
A small air intake passage 48 provided between the cover and the cover 42
(In the present embodiment, the outer shape of the perfume storage cassette 41 is made as close as possible to the inner periphery of the cover 42, and the perfume storage volume of the perfume storage cassette 41 is expanded as much as possible. Is connected to the air reservoir 51.

That is, in the fragrance device 10, if the volume of the fragrance storage cassette 41 is increased, the fragrance storage cassette 4
An air intake passage 48 to the ventilation chamber 35 formed around
Although the flow passage area must be small, when the fan 26 is operated, air is smoothly sucked from the air reservoir 51 immediately upstream, and as a result, sufficient air can be taken in. It is possible to increase the amount of air blown out from the fragrance.

FIG. 4 shows the results of an experiment using the fragrance device 10, and shows the fragrance blowing wind speed V (m / s) blown from the blowing port 37 of the blowing chamber 35 when the fan 26 rotates, and the above-mentioned air reservoir. The relationship with the volume Q (cm ³ ) of 51 is shown. As the volume of the air reservoir 51 increases, the wind speed of the fragrance blowout increases.

[0015]

According to the present invention, in the fragrance device, the volume of the fragrance blow-out air can be increased while increasing the volume of the fragrance storage section as much as possible.
